FP03-0088-00 Description NITROGEN-CONTAINING AROMATIC DERIVATIVES Technical Field [0001] The present invention relates to novel compounds effective for prevention and treatment of various diseases associated with abnormal angiogenesis, and to the medical compositions such as angiogenesis inhibitors and antitumor agents containing the novel compounds.
Background Art [0002] Angiogenesis is an essential biological phenomenon for fetal vascular formation and morphological and functional development of organs.
New blood vessels are assembled through several processes including endothelial cell migration, proliferation and tube formation, and the participation of mast cells, lymphocytes, interstitial cells and the like has been shown to be important in this process (non-patent literature 1).
[0003] A multiple in vivo angiogenesis-stimulating factors have been identified, particularly Vascular Endothelial Growth Factor (hereinafter abbreviated as "VEGF") and Fibroblast Growth Factor (hereinafter FP03-0088-00 abbreviated as "FGF") are reported to. enhance angiogenesis (non-patent literature 2 and 3).
[0004] Although physiological angiogenesis occurs at the time of healing of wound or in a female estrous cycle in adult individuals, it is known that pathological increase in angiogenesis in adult individuals is involved in onset or progression of various disease. Specific diseases associated with abnormal angiogenesis include cancer, rheumatoid arthritis, atherosclerosis, diabetic retinopathy, angioma, psoriasis, and the like (non-patent literature In particular, a literature has indicated angiogenesis dependency for solid tumor growth, and angiogenesis inhibitors are therefore promising as new therapeutic agents for intractable solid tumors (nonpatent literature [0005] Patent literature 1 and 2 are provided as prior arts with regard to 6-membered nitrogen-containing aromatic derivatives bonded with substituted indole.
[0006] Although patent literature 1 describes indole derivatives which suppress VEGF-stimulated angiogenesis based on a selective tyrosine kinase inhibition, the pharmacological test results on their inhibition action are not disclosed. Although patent literature 2 describes pyridine derivatives bonded with indole ring via an oxygen atom at the 4-position, neither the compound according to the present invention nor their inhibiting actions on FGF-stimulated angiogenesis are disclosed.

After dialysis, it was supplied for SDS-electrophoresis, and the recombinant protein (His6-VEGFR2, cytoplasmic domain of VEGFR2 fused with 6 histidine residues at the N-terminus) detected at a molecular weight of approximately 100 kDa with Coumassie Brilliant Blue staining was assayed using BSA (bovine serum albumin, purchased from Sigma Co.) as the standard substance, and stored at -80 0 C until use. Using the same method for the cytoplasmic domains of FGFR1, PDGFRP and HGFR yielded respective recombinant proteins fused with 6 histidine residues at the N-terminal (His6-FGFR1, His6- PDGFRp or His6-HGFR).

Next, pl of 4 pM ATP (diluted with distilled water) was added prior to incubation at 30 0 C for 10 minutes, and then 10 pl of 500 mM EDTA (pH 8.0) was added.
[0151] The tyrosine phosphorylated biotin-poly(GT) was measured by the Homogenous Time-Resolved Fluorescence (HTRF) method (Analytical Biochemistry, 269, 94-104, 1999). Specifically, the kinase reaction solution was transferred to a 96-well black half-plate (Product No.

The delta F% value in the presence of the test substance was determined as a ratio with the delta F% value with addition of His6-VEGFR2 in the absence of the test substance defined as 100% and the delta F% value in the absence of both the test substance and His6-VEGFR2 defined as This ratio was used to calculate the test substance concentration required for 50% inhibition of VEGFR2 kinase activity (ICs 0 [0152] Measurement of inhibition against FGFR1, EGFR and HGFR kinase activity was conducted using 15 ng of His6-FGFR1, 23 ng of EGFR and 30 ng of His6-HGFR, respectively, according to the tyrosine kinase reaction and HTRF method described above. Measurement of inhibition against PDGFRP kinase activity was conducted using 50 ng of His6-PDGFRP according to the tyrosine kinase reaction described above, followed by detection of tyrosine phosphorylated biotin-poly(GT) by the following method. Specifically, the kinase reaction solution was added to a 96-well streptavidin-coated FP03-0088-00 plate (Product No. 15129, Pierce Chemical) and incubated at room temperature for 30 minutes. After rinsing 3 times with 150 pl of a rinsing solution mM Tris-HCl (pH 137 mM NaCI, 0.05% Tween-20, 0.1% BSA}, 70 pl of anti-phosphotyrosine conjugate (Product No. P-11625, Transduction Laboratories) {2000-fold dilution with 20 mM Tris-HCl (pH 137 mM NaC1, 0.05% Tween-20, 1% BSA} was added thereto and incubation was performed at room temperature for 1 hour. After incubation, it was rinsed 3 times with 150 pl of the rinsing solution, and 100 pl of TMB Membrane Peroxidase Substrate (Product No.
50-5077-03, Funakoshi Co., Ltd.) was added to initiate the reaction. After stationing at room temperature for 10 minutes, 100 pl of 1 M phosphoric acid was added to suspend the reaction, and the absorbance at 450 nm was measured with a microplate reader (BIO KINETICS READER EL304, Bio-Tek Instruments). The absorbance ratio in the presence of the test substance was determined with respect to 100% as the absorbance with addition of His6-PDGFR( and no test substance, and 0% as the absorbance without addition of both the test substance and His6-PDGFRP. This absorbance ratio was used to calculate the test substance concentration required for 50% inhibition of PDGFRP kinase activity (ICso). The results are shown in Table 2.

[0155] Preparation of VEGF high-expressing strain After overnight culturing of KP-1 human pancreatic cancer cells (3 x 106 cells) with 10% FCScontaining RPMI 1640 medium, an Effectene Transfection Reagent Kit (Qiagen) was used for introduction of 3 pg of pIRES2-rsGFP/VEGF into the KP-1 cells. After 116 FP03-0088-00 culturing in 10% FCS-containing RPMI 1640 medium containing 600 pg/ml of Geneticin, drug-resistant cells were selected. Furthermore, GFP high-expressing cells were collected by cell sorter (Becton Dickinson) as VEGF high-expressing KP-1 cells (KP-1/VEGF).
[0156] Measurement of VEGF level in culture supernatant The KP-1/VEGF cells were prepared to 5 x 105 cells/ml, and 0.5 ml thereof was dispensed into each well of a 24-well plate and cultured at 37 0 C for 24 hours. The culture supernatants were collected and the VEGF levels thereof measured using a VEGF measuring kit (IBL Co., Ltd.) for confirmation of high expression.
[0157] Evaluation of in vivo angiogenesis-inducing activity using mouse dorsal air sac model Millipore rings (Nihon Millipore) were sealed with 0.45 um Durapore filter membranes (Nihon Millipore) to create chambers. KP-1/VEGF human pancreatic cancer cells (3 x 106) suspended in 0.17 ml of collagen gel were injected into each chamber through the injection port, and the chambers were sealed.
Approximately 10 ml of air was then injected in the dorsal skin of 6-week-old C57BL/6N female mice under anesthesia to produce pouches, and the prepared 117 FP03-0088-00 chambers were transplanted therein. About 6 hours after completing transplantation, a test substance suspended in 0.5% methyl cellulose was orally administered (0.1 ml/10 g body weight), and this was continued once a day for the next 4 days.
[0158] On the 4th day after transplanting the chambers, 0.2 ml of 1Cr (Amersham Pharmacia)-labeled mouse erythrocytes (2.5 x 106 cpm/ml) were injected through the caudal veins of each of the mice with the transplanted chambers. After a prescribed period, the skin in contact with the chamber was excised and frozen, the section in direct contact with the chamber was precisely cut off, and the radioactivity was measured with a y-counter. The blood volume was calculated from the radioactivity and used as an index of the in vivo angiogenesis-inducing activity. The angiogenesis.
volume was recorded as this measured blood volume minus the blood volume obtained with transplantation of a chamber containing only collagen gel. The experiment was conducted using 10 mice in the control (solventadministered) group and 5 mice in each compoundadministered group. The proportions of the angiogenesis amount after administering a test substance to that of control are shown in Table 3.

When the tumor volume reached approximately 100 mm 3 the test substance was orally administered twice a day over a period of 2 weeks with a schedule of 5 days per week. The test substance was suspended in 0.5% methyl cellulose for an administered volume of 0.1 ml/10 g body weight. The tumor size was measured twice a week using a micrometer caliper. The tumor volume was determined by measuring the long and short diameters of the tumor with a micrometer caliper, and calculating 1/2 x (long diameter x short diameter x short diameter). The experiment was conducted using 10 mice in the control (solvent- 119 FP03-0088-00 administered) group and 5 mice in each test substanceadministered group.

After that, a 300 pl of this mixture of Matrigel Matrix and Recombinant FGF-2 was injected into a subcutaneous tissue on the median line of the abdomen of a 6-week-old Balb/c (nu/nu) mouse.
[0163] 120 FP03-0088-00 Subsequently, the test substance suspended in a methyl cellulose or the like had been orally administered in succession once a day or twice a day for 7 days.
[0164] After 7 days, the implanted Matrigel was taken out, 300 pl of water was added thereto, and cut into pieces with scissors. The resultant substance was allowed to stand at a cool dark place overnight. After hemoglobin in Matrigel was fully extracted, 100 ul of the supernatant obtained by centrifugation and 100 pl of Drabkin's solution (purchased from Sigma Chemical Co., Ltd) were allowed to react at room temperature at a dark place for 1 hour. After that, the absorbance of the reaction solution was measured with wavelength of 550nm and reference wavelength of 660 nm. The hemoglobin quantity (g/ml) in Matrigel was calculated from the calibration curve established by use of hemoglobin as a standard.

[0532] It should be noted that the tube formation by vascular endothelial cells is an important process in angiogenesis, and compounds having inhibitory action against them therefore has angiogenesis-inhibiting action. In addition, it is known that angiogenesis in the body progresses by the additive/synergistic effect of a multiple angiogenic factors represented by VEGF and FGF (Koolwijk P, van Erck MGM, de Vree WJA, Vermeer MA, Weich HA, Hance maaijer R, van Hinsbergh VWM,.
Cooperative effect of TNF-alpha, bFGF and VEGF on the formation of tubular structures of human microvascular endothelial cells in a fibrin matrix. Role of urokinase activity. J. Cell Biol., 132 P. 1177-1188, (1996)).
[0533] Therefore, the compounds of the invention which 426 FP03-0088-00 inhibit tube formation induced by VEGF or FGF produced by cancer cells and the like are expected to exhibit powerful angiogenesis inhibition in vivo, and should be highly useful as angiogenesis inhibitors. Moreover, the compounds of the invention are highly useful as angiogenesis inhibitors, and are also useful as prophylactic or therapeutic agents for diseases for which angiogenesis inhibition is effective, angiogenesis inhibitors, antitumor agents, therapeutic agents for angioma, cancer metastasis inhibitors, therapeutic agents for retinal neovascularization, therapeutic agents for diabetic retinopathy, therapeutic agents for inflammatory disease, therapeutic agents for inflammatory disease selected from deformant arthritis, rheumatoid arthritis, psoriasis or delayed hypersensitivity reaction, therapeutic agents for atherosclerosis, and angiogenesis inhibition-based antitumor agents.
[0534] In addition, when using the compounds of the invention as antitumor agents, the tumors include, for example, a pancreatic cancer, a gastric cancer, a colon cancer, a breast cancer, a prostate cancer, a lung cancer, a renal cancer, a brain tumor, a blood cancer and an ovarian cancer; and the tumors to be suitably targeted are a gastric cancer, a colon cancer, a 427 FP03-0088-00 prostate cancer or a renal cancer.
